30 posts in a day might creates too much useless comments and that's why you got banned, just stop asking meaningless questions here and wait for 30 days, you will be able to post again.
Also I highly suggest taking the time off from the board. If you create a new account as some might be tempted to do during ban it's considered ban evasion and is a perm ban.
So don't try to create a new account if you think as many do to thy this during temp ban.
